This multi-core power cable is constructed with copper conductors, XLPE insulation, and a copper tape metallic screen, combined with steel wire armour for enhanced mechanical strength.
The cable structure supports stable electrical performance while providing reinforced protection, making it suitable for medium voltage power distribution environments where external mechanical influence may occur.
The use of PVC inner and outer sheaths contributes to overall cable integrity, while the assembled core design improves structural stability in multi-core configurations.
